Characteristics of bituminous binders utilizing pulverized rubber and its use for bitumen modification

Popis výsledku v původním jazyce

The use of crumb rubber is in road construction a well established technology, whereas in the last decade various technical solutions were introduced and innovated with use of this additive or admixture mainly for the production of modified bituminous binders, which can be classified somewhere between straight-run bi-tumen and polymer modified bitumen based on their performance behavior and functional characteristics. Last 4 years the attention of the cooperation between the Faculty of Civil Engineering CTU Prague and two industrial partners specialized in the high-speed grinding was focused intensively on the possibility to in-crease efficiency of waste rubber application in bituminous binders. This should be given by a suitable treatment of rubber and the achievement of particular variants of fine-grinded rubber with particle size in the range of 0-0.8 mm. Partial effort is to determine the possibility of using the disintegrator not only for milling the rubber but also to parallel mixing of bitumen with grinded rubber, i.e. achieving resulting CRmB binder in one step. For this reason experimental comparison was done with use of one source of crumb rubber. From this rubber experimental (semi-production) samples of mixed rubber-bitumen composite were prepared. At the same time also standardized production of crumb rubber modified bitumen (CRmB) was done. Selected type of pulverized rubber was mixed with hot bitumen. Experimental options of bituminous binders were compared with respect to their empirical characteristics and performance-based (functional) properties. These properties contain mainly multiple-stress creep recovery test, determination of complex shear modu-lus at different temperatures and dynamic viscosity measures.
